Abstract
Description
- This application is a continuation of International Application No. PCT/KR2022/010470 designating the United States, filed on Jun. 18, 2022, in the Korean Intellectual Property Receiving Office and claiming priority to Korean Patent Application No. 10-2021-0093560, filed on Jul. 16, 2021, in the Korean Intellectual Property Office, the disclosures of all of which are incorporated by reference herein in their entireties.
- Various embodiments of the disclosure relate to an electronic device, and more particularly, to an electronic device including a geomagnetic sensor, which is capable of determining whether a cover is coupled with (attached to or detached from) the electronic device, along with determining magnetic north.
- As information and communication technologies and semiconductor technologies have developed, the various types of electronic devices have been widespread and used at a rapid pace. Particularly, recent electronic devices are being developed such that communication may be conducted while the electronic devices are carried. In addition, the electronic devices may output stored information as sound or an image. As the integration level of the electronic devices increases and high-speed and large-capacity wireless communication becomes common, a single electronic device such as a mobile communication terminal may be equipped with various functions in recent years. For example, entertainment functions such as games, multimedia functions such as music/video playback, communication and security functions for mobile banking, schedule management, and electronic wallet functions as well as communication functions are integrated into a single electronic device. Such electronic devices are being miniaturized so that users may conveniently carry them.
- Since the exterior of an electronic device and electronic components included in the electronic device are vulnerable to external physical and chemical impacts, a cover (e.g., an accessory case) for protecting them is widely used.
- According to some embodiments, to detect whether a cover is attached to an electronic device, the cover may include a magnetic member, and a sensor (e.g., a hall integrated circuit (IC) sensor) for detecting whether the magnetic member is in proximity may be attached to the electronic device. When the cover is attached to the electronic device, a hall effect may be generated by the magnetic member of the cover, and the hall IC sensor of the electronic device may generate a signal corresponding to the hall effect. A processor included in the electronic device may receive the signal generated from the hall IC sensor to identify whether the cover has been attached. As such, it is conventionally determined whether the cover has been attached by using a magnetic force generated between the magnetic member and the hall IC sensor corresponding to the magnetic member. However, the performance of a plurality of electronic components disposed inside the electronic device may be directly affected by the magnetic force between the magnetic member and the hall IC sensor and significantly degraded in some cases. For example, the magnetic force between the magnetic member and the hall IC sensor may interfere with radio waves of an antenna attached inside the electronic device, thereby degrading the performance. Moreover, the hall IC sensor for detecting the magnetic force of the magnetic member of the cover may have a limited mounting space in a small electronic device such as a smart phone. That is, the magnetic member and the sensor for determining whether the cover has been attached may impose a constraint on the design of the electronic device.
- According to various embodiments of the disclosure, a means for determining whether a cover is coupled with (attached to or detached from) an electronic device without a hall IC sensor in the electronic device, and a method of determining the same are provided.
- According to various embodiments, an electronic device combinable with a cover for protecting the electronic device may include: a housing including a first surface facing a first direction; and a second surface facing a second direction opposite to the first direction, wherein an inner space is formed between the first surface and the second surface; a board disposed in the inner space; a geomagnetic sensor disposed on the board; and a processor. The geomagnetic sensor may be configured to detect a first magnetic force, when a first cover part of the cover, including a first magnetic member, is disposed to cover the first surface from the first direction of the electronic device, and detect a second magnetic force, when a second cover part of the cover, including a second magnetic member, is disposed to cover the second surface from the second direction of the electronic device in a state where the first cover part is disposed to cover the first surface from the first direction of the electronic device. The processor may be configured to determine whether the cover is coupled with the electronic device, along with determining magnetic north, based on information about a magnetic force detected by the geomagnetic sensor.
- According to various embodiments, in a method of controlling an electronic device including a display, an antenna, a geomagnetic sensor, and a processor, and combinable with a cover, based on a magnetic force measured by the geomagnetic sensor, when a first magnetic force greater than a predetermined value is detected from a first direction, determining, by the processor, that a first cover part of the cover is coupled with the electronic device and performing a wireless authentication operation, and when a second magnetic force greater than a predetermined value is detected from a second direction after the cover is identified as genuine according to the wireless authentication operation, determining, by the processor, that a second cover part of the cover covers at least a part of the display of the electronic device and performing an operation of deactivating the at least part of the display.
- According to various embodiments, an electronic device may include: a housing including a first surface facing a first direction; and a second surface facing a second direction opposite to the first direction, wherein an inner space is formed between the first surface and the second surface; a board disposed in the inner space; a geomagnetic sensor disposed on the board; and a cover configured to protect the electronic device, and including a first cover part for covering the first surface of the electronic device and a second cover part for covering the second surface of the electronic device; a first magnetic member disposed at a first position of the first cover part; and a second magnetic member disposed at a second position of the second cover part. The first position of the first magnetic member may be set to a position at which a first magnetic force acts on the geomagnetic sensor, when the first cover part is disposed to cover the first surface from the first direction of the electronic device, and the second position of the second magnetic material may be set to a position at which a second magnetic force acts on the geomagnetic sensor, when the second cover part is disposed to cover the second surface from the second direction of the electronic device in a state in which the first cover part is disposed to cover the first surface from the first direction of the electronic device.
- According to various embodiments, an electronic device may include: a housing; a board disposed in an inner space of the housing; a geomagnetic sensor disposed on the board; and a processor. The geomagnetic sensor may be configured to detect a first magnetic force from a first direction or a second magnetic force from a second direction from each of a first magnetic member and a second magnetic member which are disposed inside the housing or in a cover covering at least a part of the housing, spaced apart from the geomagnetic sensor by a specified distance and have variable positions. The processor may be configured to be capable of determining whether the cover is coupled with the electronic device or various motions of the electronic device, along with determining magnetic north, based on information about the magnetic force detected by the geomagnetic sensor.
- According to various embodiments of the disclosure, it may be determined whether a cover has been attached to an electronic device without a hall integrated circuit (IC) sensor.

For example, the illustrated electronic device may be a part of a rollable electronic device or foldable electronic device. A “rollable electronic device” refers to an electronic device in which a display (e.g., thedisplay 230 ofFIG. 3 ) is bendable to be deformed and thus partially wound or rolled or accommodated in a housing (e.g., thehousing 210 ofFIG. 2 )). According to a user need or interest, the rollable electronic device may increase a view area by unfolding the display or exposing a larger area of the display to the outside. A “foldable electronic device” may refer to an electronic device in which a display is foldable such that two different areas of the display face each other or in opposite directions. In general, the display may be folded with two different areas facing each other or in opposite directions in a portable state, whereas the user may unfold the display with the two different areas of the display being substantially flat in an actual use state, in the foldable electronic device. In some embodiments, theelectronic device 101 according to various embodiments of the disclosure may be interpreted as including not only a portable electronic device such as a smart phone, but also various other electronic devices such as a laptop computer or a home appliance. -
FIG. 4 illustrates a diagram illustrating acover 300 attachable to an electronic device according to various embodiments. - According to various embodiments, the
cover 300 may be a cover manufactured integrally with a part (e.g., a rear plate) of a housing of an electronic device (e.g., theelectronic device 101 ofFIGS. 1 to 3 ) to be a part of theelectronic device 101, or an accessory cover that is manufactured separately from the electronic device and coupled with the electronic device. In describing various embodiments of the disclosure, “couple”′ may include any form in which a first component is physically connected to a second component, such as mounting, attachment, and so on, and any form in which the first component is removed (detached) from the second component and reattached to the second component after the combination. The following embodiments will be given in the context of an accessory cover as a separate component combinable with an electronic device, for convenience. - Referring to
FIG. 4 , thecover 300 may include afirst cover part 310 for covering at least a part of an electronic device (e.g., theelectronic device 101 ofFIGS. 1 to 3 ) and asecond cover part 320 that covers at least a part of theelectronic device 101 and is foldable (or rotatable) with respect to thefirst cover part 310. Thefirst cover part 310 and thesecond cover part 320 may be rotatably coupled to each other by a connectingmember 330. Theelectronic device 101 illustrated inFIGS. 2A, 2B and 3 is a bar type, and according to an embodiment, thefirst cover part 310 may be a part substantially coupled with (or attached to) a housing of the electronic device and fixed to the housing, and thesecond cover part 320 may be a part of a flip cover, which may cover or open substantially the entire display part of the electronic device. According to other embodiments, while not shown in the drawings, when theelectronic device 101 includes an extendable display (e.g., when theelectronic device 101 is a foldable electronic device including a first housing structure and a second housing structure), thefirst cover part 310 may be formed to at least partially cover a part (e.g., the first housing structure) of theelectronic device 101, and thesecond cover part 320 may be formed to at least partially cover the other part (e.g., the second housing structure) of theelectronic device 101. - The
cover 300 may be fully unfolded, at least partially folded, or fully folded. This may mean that thefirst cover part 310 and thesecond cover part 320 may be fully unfolded, at least partially folded, or fully folded with respect to each other. When it is said that thefirst cover part 310 and thesecond cover part 320 are fully unfolded, this may mean that thefirst cover part 310 and thesecond cover part 320 are located on substantially the same plane (e.g., an XY plane). When it is said that thefirst cover part 310 and thesecond cover part 320 are fully folded, this may mean that thefirst cover part 310 and thesecond cover part 320 are stacked in one direction (e.g., in a Z-axis direction), which includes placing thesecond cover part 320 on thefirst cover part 310, that is, in-folding or placing thefirst cover part 320 on thesecond cover part 320, that is, out-folding. When it is said that thefirst cover part 310 and thesecond cover part 320 are at least partially folded with respect to each other, it may mean an intermediate state between the fully unfolded state and the fully folded state. -
FIG. 4 illustrates the fully unfolded state between thefirst cover part 310 and the second cover part 320 (hereinafter, referred to as a “third state” (or “second open state”)). With reference toFIGS. 5 and 6 to be described later, a folded-in state (referred to as a “first state” (or “closed state”)) and a folded-out state (referred to as a “second state” (or “first open state”)) between thefirst cover part 310 and thesecond cover part 320 will be described in more detail. Although the intermediate state (referred to as a “fourth state”) in which thefirst cover part 310 and thesecond cover part 320 are at least partially folded with respect to each other is not shown separately, the description of the third state may be applied to the fourth state. - The
cover 300 may form an inner space for accommodating theelectronic device 101 on one side (e.g., the first cover part 310), and when theelectronic device 101 is accommodated in the inner space, one surface (e.g., the front surface of the display) of theelectronic device 101 may be exposed to the outside. According to an embodiment, atransparent member 322 may be provided in thesecond cover part 320, so that even when thesecond cover part 320 is folded in with respect to thefirst cover part 310, the one surface of theelectronic device 101 may be exposed to the outside. According to an embodiment, thecover 300 may further include at least oneopening 323, and even when thesecond cover part 320 is folded in with respect to thefirst cover part 310, an incoming or outgoing call may be made through the at least oneopening 323. The sizes, positions, and numbers of thetransparent member 322 and theopening 323 may vary from one embodiment to another, not limited to any specific embodiment including the embodiments shown in the drawings. - The
cover 300 may be configured to protect theelectronic device 101 from external impacts (e.g., physical and chemical impacts). According to various embodiments, thecover 300 may be formed to have a size corresponding to the size and specification of theelectronic device 101. In addition, thecover 300 may be formed in various colors or textures to make the appearance of the electronic device enhanced, thereby revealing a user's personality. Accordingly, the user may attach thecover 300 to theelectronic device 101 in order to diversify the exterior design. In this way, thecover 300 may be used not only for the purpose of protecting theelectronic device 101 but also as a means for increasing the variety of exterior designs. The design of thecover 300 as well as the appearance of theelectronic device 101 may be a very important factor in terms of customer attraction. Accordingly, according to various embodiments of the disclosure, thecover 300 is given a unique identifier (ID) for a certificate of authenticity, and theelectronic device 101 may be provided with a component (e.g., an antenna (e.g., theantenna 270 ofFIG. 3 )) that identifies the unique ID of thecover 300. For example, thecover 300 may include awireless authentication module 312 that stores information about the unique ID and performs a wireless authentication operation with an antenna module (e.g., theantenna module 197 ofFIG. 1 ) of theelectronic device 101. According to an embodiment, thewireless authentication module 312 may be disposed in thefirst cover part 310 combinable with the housing of theelectronic device 101. - According to various embodiments of the disclosure, when the
cover 300 is attached to theelectronic device 101, at least some of the functions of theelectronic device 101 may be activated (e.g., wake-up mode) or deactivated (e.g., sleep mode) according to the arrangement state of thecover 300 and theelectronic device 101. - According to an embodiment, when the
second cover part 320 is folded in with respect to thefirst cover part 310 and covers substantially one surface (e.g., the front surface of the display) of theelectronic device 101, theelectronic device 101 may be considered to be in an unused state, for example, the sleep mode, and thus the display may be deactivated. However, even when thesecond cover part 320 is folded in with respect to thefirst cover part 310 and covers substantially the one surface (e.g., the front surface of the display) of theelectronic device 101, a part of the display and a screen displayed on the display may be exposed to the outside through thetransparent member 322. For example, information about the position of thetransparent member 322 of thecover 300 may also be identified during authentication of thecover 300, and thus a processor (e.g., theprocessor 120 inFIG. 1 ) may activate a part of the display corresponding to the position of thetransparent member 322 and deactivate the remaining part of the display. - According to other embodiments, when the
second cover part 320 is folded out with respect to thefirst cover part 310 and covers the other surface (e.g., the rear surface) of theelectronic device 101, theelectronic device 101 may be considered to be in a used state, for example, the wake-up mode, and the display may be activated. Depending on the arrangement state of thecover 300 and theelectronic device 101, at least some of the functions of theelectronic device 101 may be activated (e.g., the wake-up mode) or deactivated (e.g., the sleep mode), thereby increasing use convenience. To this end, thecover 300 may include a magnetic member as a means for determining an arrangement relationship with theelectronic device 101. - The
cover 300 may include a firstmagnetic member 311 in thefirst cover part 310 and a secondmagnetic member 321 in thesecond cover part 320. According to an embodiment, the firstmagnetic member 311 may be provided to identify whether theelectronic device 101 has been coupled with (or attached to or detached from) thefirst cover part 310, when thefirst cover part 310 of thecover 300 and theelectronic device 101 are coupled with each other. The secondmagnetic member 321 may be provided whether thesecond cover part 310 is in the first state (the folded-in state) with respect to thefirst cover part 310 or in the second state (the folded-out state) with respect to thefirst cover part 310. It may be identified whether thesecond cover part 320 is in the first state or in the second state with respect to thefirst cover part 310, after theelectronic device 101 is coupled with thefirst cover part 310. -
FIG. 5 illustrates a cross-sectional view illustrating thecover 300 attached to theelectronic device 101 according to the first state (the folded-in state).FIG. 6 illustrates a cross-sectional view illustrating thecover 300 attached to theelectronic device 101 according to the second state (the folded-out state). - Referring to
FIGS. 5 and 6 together, theelectronic device 101 may include thehousing 210 which includes afirst surface 210B facing a first direction (e.g., a +Z direction) and asecond surface 210A facing a second direction (e.g., a −Z direction) opposite to thefirst surface 210B, with an inner space S between thefirst surface 210B and thesecond surface 210A, a board 240 (e.g., themain PCB 240 ofFIG. 3 ) disposed in the inner space S, ageomagnetic sensor 245 disposed on theboard 240, and a processor (e.g., theprocessor 120 ofFIG. 1 ). - According to various embodiments, the
housing 210 may be substantially identical to thehousing 210 described with reference toFIGS. 2A and 2B , and may provide thesecond surface 210A by thedisplay 201 and thefirst surface 210B by therear plate 280. According to an embodiment, thehousing 210 may further include theside bezel structure 231, the second support member 260 (the rear case), and therear plate 280. While therear plate 280 is shown as separated from theside bezel structure 231 and thesecond support member 260 inFIGS. 5 and 6 , the disclosure is not limited thereto. Various embodiments may be available, such as integration of therear plate 280 and thesecond support member 260 and integration of thesecond support member 260 and theside bezel structure 231. - According to various embodiments of the disclosure, without a separate hall IC, the
electronic device 101 may determine whether thecover 300 has been attached or detached by identifying whether a magnetic member disposed on thecover 300 is in proximity by using thegeomagnetic sensor 245 in the inner space S of thehousing 210. - According to an embodiment, when the
first cover part 310 including the firstmagnetic member 311 is disposed to cover thefirst surface 210B from the first direction (e.g., the +Z direction) of theelectronic device 101, thegeomagnetic sensor 245 may detect a first magnetic force, and when thesecond cover part 320 including the secondmagnetic member 321 is disposed to cover thesecond surface 210A from the second direction (e.g., the −Z direction) of the electronic device, thegeomagnetic sensor 245 may detect a second magnetic force. In this case, the processor (e.g., theprocessor 120 ofFIG. 1 ) may identify whether the cover has been attached to or detached from theelectronic device 101, along with determining magnetic north based on information about the identified magnetic forces. - For example, the
geomagnetic sensor 245 may detect the first magnetic force, which is the sum of a magnetic force from the firstmagnetic member 311 at a fixed position in a state in which theelectronic device 101 is coupled with thefirst cover part 310 and a magnetic force from the secondmagnetic member 321 at a variable position. The first magnetic force may be the sum of the magnetic force of the firstmagnetic member 311 and the magnetic force of the secondmagnetic member 321, which are measured in a state where thesecond cover part 320 does not cover either of thesecond surface 210A or thefirst cover part 310, that is, in the third state (the fully unfolded state) or the fourth state (the intermediate state). - According to an embodiment, the first magnetic force may include information about a direction in which a magnetic field is formed. For example, the first magnetic force is a value measured when the
first cover part 310 including the firstmagnetic member 311 is attached to thefirst surface 210B of theelectronic device 101, and may include information about a first direction formed with respect to thegeomagnetic sensor 245. In the third state (the fully unfolded state) or the fourth state (the intermediate state), the secondmagnetic member 321 may affect thegeomagnetic sensor 245 negligibly or slightly, compared to the firstmagnetic member 311. That is, while the firstmagnetic member 311 is dominantly affecting thegeomagnetic sensor 245, the processor (e.g., theprocessor 120 ofFIG. 1 ) may identify the magnetic force measured at thegeomagnetic sensor 245 as the first magnetic force and determine that the cover 300 (e.g., the first cover part 310) has been attached to theelectronic device 101. According to various embodiments, when determining that theelectronic device 101 and thecover 300 are coupled with each other, the processor (e.g., theprocessor 120 ofFIG. 1 ) may perform a wireless authentication operation for determining whether thecover 300 is genuine, based on information received from a wireless authentication module (e.g., thewireless authentication module 312 ofFIG. 4 ). According to various embodiments, information about the first magnetic force and instructions for performing the operation, when the first magnetic force value is identified, may be pre-stored in a memory (e.g., thememory 130 ofFIG. 1 ). - In another example, the
geomagnetic sensor 245 may detect the second magnetic force, which is the sum of a magnetic force from the firstmagnetic member 311 at a fixed position in a state in which theelectronic device 101 is coupled with thefirst cover part 310 and a magnetic force from the secondmagnetic member 321 at a fixed position in a state in which thesecond cover part 320 covers thesecond surface 210A of theelectronic device 101, that is, in the first state (the folded-in state). - Referring to
FIG. 5 , thegeomagnetic sensor 245 is shown as detecting the second magnetic force, while thesecond cover part 320 covers thesecond surface 210A of theelectronic device 101. Thegeomagnetic sensor 245 may be affected by the magnetic force of the secondmagnetic member 321 as well as the magnetic force of the firstmagnetic member 311, and the magnetic force (e.g., the second magnetic force) in this case may have different magnitude and direction components from those of the first magnetic force. According to some embodiments, the second magnetic force may also include information about a direction in which the magnetic field is formed. For example, the second magnetic force may be a value measured when thesecond cover part 320 including the secondmagnetic member 321 is located on thesecond surface 210A of theelectronic device 101, and may include information about a second direction formed with respect to thegeomagnetic sensor 245. - According to various embodiments, when identifying the second magnetic force different from the first magnetic force, the processor (e.g., the
processor 120 ofFIG. 1 ) may perform an operation other than the aforementioned wireless authentication operation. For example, when identifying the second magnetic force, the processor may deactivate the entire display or activate only a part of the display, considering that thesecond cover part 320 covers thesecond surface 210A of theelectronic device 101 and thus the user does not recognize visual information to be displayed on the display. When only part of the display is activated, a screen displayed on the display may be exposed to the outside through a transparent member (e.g., thetransparent member 322 ofFIG. 4 ). In addition to the above-described operation, various embodiments are available for operations that the processor may perform, when the second magnetic force is identified. In addition, the information about the second magnetic force and instructions for performing the operation, when the second magnetic force is identified, may also be pre-stored in the memory (e.g., thememory 130 ofFIG. 1 ). - According to an embodiment, when the second cover part 329 is disposed to cover the
first cover part 310 from the first direction (e.g., the +Z direction) of theelectronic device 101 in the state where thefirst cover part 310 including the firstmagnetic member 311 is disposed to cover thefirst surface 210B from the first direction (e.g., the +Z direction) of theelectronic device 101, that is, in the second state (the folded-out state), thegeomagnetic sensor 245 may detect a third magnetic force. For example, referring toFIG. 6 , thegeomagnetic sensor 245 may detect the third magnetic force, which is the sum of a magnetic force from the firstmagnetic member 311 at a fixed position in the state where theelectronic device 101 is coupled with thefirst cover part 310 and a magnetic force from the secondmagnetic member 321 at a fixed position in the state where thesecond cover part 320 covers thefirst cover part 310. In the embodiment illustrated inFIG. 6 , thegeomagnetic sensor 245 may be affected by the magnetic force from the secondmagnetic member 321 as well as the magnetic force from the firstmagnetic member 311, and the magnetic force (e.g., the third magnetic force) in this case may have different magnitude and direction components from those of the first and second magnetic forces. According to an embodiment, the third magnetic force may also include information about a direction in which a magnetic field is formed. For example, the third magnetic force may be a value measured when thesecond cover part 320 including the secondmagnetic member 321 is located on thefirst cover part 310 attached to theelectronic device 101, and may include information about the first direction formed with respect to thegeomagnetic sensor 245. - According to various embodiments, the first
magnetic member 311 may include a (1-1)th pole 311 a facing theelectronic device 101 and a (1-2)th pole 311 b facing in a direction opposite to the (1-1)th pole 311 a, and the secondmagnetic member 321 may include a (2-1)th pole 321 a and a (2-2)th pole 321 b, which face theelectronic device 101, in the state where thecover 300 is attached to theelectronic device 101. According to an embodiment, the (1-1)th pole 311 a and the (1-2)th pole 311 b may be formed to have different polarities. For example, when the (1-1)th pole 311 a is an N pole, the (1-2)th pole 311 b may be an S pole. In the embodiment illustrated inFIG. 6 , the third magnetic force acting on thegeomagnetic sensor 245 may be greater than the first magnetic force and the second magnetic force due to the firstmagnetic member 311 and the secondmagnetic member 321 oriented in the same polarity direction. According to various embodiments, when identifying the third magnetic force, the processor (e.g., theprocessor 120 ofFIG. 1 ) may perform an operation other than the aforementioned wireless authentication operation. For example, when identifying the third magnetic force, the processor may perform an operation of activating the entire display, considering that the user may use the display. Various embodiments are available for operations that the processor may perform when the third magnetic force is identified. In addition, information about the third magnetic force and instructions for performing the operation when the third magnetic force value is identified may also be pre-stored in the memory (e.g., thememory 130 ofFIG. 1 ). - The electronic device according to various embodiments of the disclosure may be provided to perform a function of determining magnetic north as well as a cover identification function without a separate hall IC by applying the
geomagnetic sensor 245 attached for determining magnetic north and a structure in which the magnetic members having different polarities are attached to thecover 300. -
FIG. 7A illustrates a conceptual diagram illustrating a method of disposing two different magnetic members according to embodiment.FIG. 7B illustrates a conceptual diagram illustrating a method of disposing two different magnetic members according to other embodiments. - The first
magnetic member 311 disposed in thefirst cover part 310 and the secondmagnetic member 321 disposed in thesecond cover part 320 may be freely disposed in the cover. However, when the magnetic members are too close to thegeomagnetic sensor 245, an azimuth error of thegeomagnetic sensor 245 may occur. Accordingly, the firstmagnetic member 311 and the secondmagnetic member 321 may be disposed at positions that do not affect an operation of determining magnetic north. A threshold that affects the magnetic north determination operation from thegeomagnetic sensor 245 may be set for each of three axes (X, Y, and X axes), and the firstmagnetic member 311 and the secondmagnetic member 321 may be disposed at distances (separation distances) that do not exceed the threshold. - According to an embodiment, the first
magnetic member 311 and the secondmagnetic member 321 may be disposed at symmetrical positions with respect to thegeomagnetic sensor 245, as illustrated inFIG. 7A , or at positions spaced apart from each other by predetermined distances d1 and d2 from a level at which thegeomagnetic sensor 245 is disposed, as illustrated inFIG. 7B . The distance d1 between the firstmagnetic member 311 and the level may be equal to or different from the distance d2 between the secondmagnetic member 321 and the level. The firstmagnetic member 311 and the secondmagnetic member 321 may be placed at various positions according to the magnitude of a magnetic force of each magnetic member and various motions of thesecond cover part 320 rotatable with respect to thefirst cover part 310. -
FIG. 8A illustrates a conceptual diagram illustrating a method of disposing the firstmagnetic member 311 with respect to thegeomagnetic sensor 245 according to various embodiments.FIG. 8B illustrates a conceptual diagram illustrating a method of disposing the secondmagnetic member 321 with respect to thegeomagnetic sensor 245 according to various embodiments. -
FIGS. 8A and 8B illustrate a method of setting the positions of the firstmagnetic member 311 and the secondmagnetic member 321 with respect to thegeomagnetic sensor 245 in a three-axis (X, Y, and Z-axis) spatial coordinate system. - According to an embodiment, the
geomagnetic sensor 245 may be formed to be capable of determining magnetic north, regardless of whether thecover 300 is coupled with (attached to or detached from) theelectronic device 101, and whether theelectronic device 101 is placed in the first state (the folded-in state), the second state (the folded-out state), the third state (the fully unfolded state), or the fourth state (the intermediate state) after thecover 300 is coupled with theelectronic device 101. However, the firstmagnetic member 311 and the secondmagnetic member 321 may be configured to be disposed at positions spaced apart from each other on each axis in the three-axis (X, Y, and Z-axis) spatial coordinate system, to prevent an azimuth error in determining magnetic north by thegeomagnetic sensor 245. - A guide for disposing the first
magnetic member 311 is illustrated inFIG. 8A , and a guide for disposing the secondmagnetic member 321 is illustrated inFIG. 8B . The firstmagnetic member 311 may be disposed at various positions P1, P2, and P3 around thegeomagnetic sensor 245, and the secondmagnetic member 321 may also be disposed at various positions Q1, Q2, and Q3 around thegeomagnetic sensor 245. The firstmagnetic member 311 and the secondmagnetic member 321 may be located outside minimum physical separation distances d3 and d4 (e.g., 2 mm) from thegeomagnetic sensor 245 in consideration of the mobility of the cover. Further, the firstmagnetic member 311 and the secondmagnetic member 321 should be disposed at positions that minimize magnetic field interference with thegeomagnetic sensor 245, which may be achieved by placing different magnetic members in two axial directions in the three-axis spatial coordinate system. For example, the firstmagnetic member 311 may be disposed at a position where a 1000 μT magnetic force is measured in the X-axis direction, and the secondmagnetic member 321 may be disposed at a position where a −1000 μT magnetic force is measured in the Y-axis direction. In this case, the position of the firstmagnetic member 311 and the magnetic force value at the position may be set as a baseline, and the mounting position of the secondmagnetic member 321 may be determined based on the baseline. As the firstmagnetic member 311 and the secondmagnetic member 321 are disposed to form dominant magnetic forces in different axial directions in this manner, magnetic field interference with thegeomagnetic sensor 245 may be minimized, while changes in the magnetic force of thesecond cover part 320 in various states (the first to fourth states) with respect to thefirst cover part 310 may be easily tracked, thereby identifying a genuine cover and opening and closing of the cover. - According to various embodiments, to identify the
genuine cover 300, magnetic members may be arranged at different positions for different genuine covers as various types of accessories. Alternatively or additionally, magnetic members with different magnetic force magnitudes may be arranged for different genuine covers. The processor (e.g., theprocessor 120 ofFIG. 1 ) may determine which cover has been coupled with theelectronic device 101 based on different magnetic force values measured in the three-axis spatial coordinate system by thegeomagnetic sensor 245. In some genuine covers, for example, the firstmagnetic member 311 may be disposed at a position where a 1000 μT magnetic force is measured in the X-axis direction from thegeomagnetic sensor 245, and the secondmagnetic member 321 may be disposed at a position where a −1000 μT magnetic force is measured in the Y-axis direction from thegeomagnetic sensor 245. In contrast, the firstmagnetic member 311 may be disposed at a position where a 500 μT magnetic force is measured in the X-axis direction from thegeomagnetic sensor 245, and the secondmagnetic member 321 may be disposed at a position where a 1000 μT magnetic force is measured in the Y-axis direction and a 500 μT magnetic force is measured in the Z-axis direction from thegeomagnetic sensor 245, in another genuine cover. Various other embodiments may be applied. -
FIG. 9 illustrates a diagrams illustrating various embodiments of a method of applying a correction coefficient, when a processor determines magnetic north. - Diagram (a) in
FIG. 9 illustrates the third state (the state in which thefirst cover part 310 and thesecond cover part 320 are fully unfolded), diagram (b) inFIG. 9 illustrates the first state (the folded-in state) and diagram (c) inFIG. 9 illustrates the second state (the folded-out state). - When determining magnetic north based on information about a magnetic force identified by the
geomagnetic sensor 245, the processor (e.g., theprocessor 120 ofFIG. 1 ) may increase the accuracy of the magnetic north determination by applying a correction coefficient according to each of various states of thesecond cover part 320 with respect to thefirst cover part 310. For example, in the first state (the folded-in state), the processor may apply a first correction coefficient A in consideration of the influence of the first magnetic member (e.g., the firstmagnetic member 311 ofFIG. 5 ) during magnetic north determination of thegeomagnetic sensor 245, the influence of a wireless authentication module (e.g., thewireless authentication module 312 ofFIG. 4 ) during genuine product authentication, and the influence of the second magnetic member (e.g., the secondmagnetic member 321 ofFIG. 5 ). In the second state (the folded-out state), for example, the processor may apply a second correction coefficient B in consideration of the influence of the first magnetic member (e.g., the firstmagnetic member 311 ofFIG. 6 ) during magnetic north determination of thegeomagnetic sensor 245, the influence of the wireless authentication module (e.g., thewireless authentication module 312 ofFIG. 4 ) during genuine product authentication, and the influence of the second magnetic member (e.g., the secondmagnetic member 321 ofFIG. 6 ). In the third state (the fully unfolded state of thefirst cover part 310 and the second cover part 320) or the fourth state (the intermediate state), for example, the processor may apply a third correction coefficient C in consideration of the influence of the first magnetic member (e.g., the firstmagnetic member 311 ofFIG. 4 ) during magnetic north determination of thegeomagnetic sensor 245 and the influence of the wireless authentication module (e.g., thewireless authentication module 312 ofFIG. 4 ) during genuine product authentication. -
FIG. 10 illustrates a flowchart illustrating a method of controlling an electronic device according to various embodiments of the disclosure. - According to various embodiments of the disclosure, a method of controlling an electronic device (e.g., the
electronic device 101 ofFIG. 1 ) including a display (e.g., thedisplay 201 ofFIG. 5 ), an antenna (e.g., theantenna 270 ofFIG. 3 ), a geomagnetic sensor (e.g., thegeomagnetic sensor 245 ofFIG. 5 ), and a processor (e.g., theprocessor 120 ofFIG. 1 ), and combinable with a cover (e.g., thecover 300 ofFIG. 4 ) may be provided. - The method of controlling an electronic device illustrated in
FIG. 10 may be performed by theprocessor 120 based on a magnetic force measured in real time by thegeomagnetic sensor 245. The magnetic force measured by thegeomagnetic sensor 245 may include information about a direction of a magnetic field as well as a magnitude of the magnetic field. - In relation to operation S1010, the
processor 120 may determine whether a first magnetic force greater than a predetermined value is detected from a first direction. The first direction may mean the +Z-axis direction in the embodiment illustrated inFIG. 5 . The “predetermined value” may be a value stored in a memory (e.g., thememory 130 ofFIG. 1 ). Upon detection of the first magnetic force greater than the predetermined value from the first direction, theprocessor 120 may perform a wireless authentication operation, determining that the first cover part (e.g., thefirst cover part 310 ofFIG. 4 ) of thecover 300 has been coupled with theelectronic device 101. - In relation to operations S1020 and S1030, the wireless authentication operation may be performed between the
antenna 270 of theelectronic device 101 and the wireless authentication module (e.g., thewireless authentication module 312 ofFIG. 4 ) of thecover 300. Information about a unique ID for genuine product authentication may be stored in thewireless authentication module 312. This information may be received through theantenna 270 and analyzed by theprocessor 120 to determine whether thecover 300 is genuine. According to an embodiment, theelectronic device 101 may further include a genuine product identification module and identify or authenticate whether thecover 300 is genuine by using genuine product information stored in the genuine product identification module. - When the
cover 300 is identified as genuine, theprocessor 120 may determine whether a second magnetic force greater than a predetermined value has been detected from the second direction in relation to operation S1040. The second direction may mean the −Z-axis direction in the embodiment illustrated inFIG. 5 . The “predetermined value” may be a value stored in thememory 130. When the second magnetic force greater than the predetermined value has been detected from the second direction, it may be considered that the second cover part of the cover 300 (e.g., thesecond cover part 320 ofFIG. 4 ) has covered the display (e.g., thedisplay 201 ofFIG. 5 ) of theelectronic device 101. In relation to operation S1050, at least a part of the display may be deactivated. When a transparent member (e.g., thetransparent member 322 ofFIG. 3 ) is formed on thesecond cover part 320, theprocessor 120 may perform an operation of activating the part of the display and deactivating the other part by reflecting information about the position of the transparent member. - When identifying the
cover 300 as genuine, theprocessor 120 may determine whether a third magnetic force greater than a predetermined value has been detected from the first direction in relation to operation S1060. The “predetermined value” may be a value stored in thememory 130. When the third magnetic force greater than the predetermined value has been detected from the first direction, it may be considered that with thefirst cover part 310 of thecover 300 coupled with theelectronic device 101, thesecond cover part 320 has covered thefirst cover part 310. In this case, it is assumed that the user uses theelectronic device 101, and the display may be deactivated, in relation to operation S1070. - The processor may perform a function of determining magnetic north, together with the determination as to whether the
first cover part 310 has been coupled with theelectronic device 101, whether thesecond cover part 320 covers at least a part of thedisplay 201 of theelectronic device 101, and whether thesecond cover part 320 covers thefirst cover part 310, through the geomagnetic sensor. In this case, when determining the magnetic north, the processor may apply a correction coefficient according to whether the cover has been coupled with the electronic device. - According to various embodiments of the disclosure, because it may be determined whether the cover is attached to the electronic device without a hall IC sensor, performance degradation of various electronic components included in the electronic device may be prevented. Further, the electronic device determines whether the cover has been attached by means of another sensor (e.g., the geomagnetic sensor) disposed in the electronic device, without including a separate sensor for measuring a magnetic force (e.g., the hall IC sensor). Therefore, difficulty in mounting components inside the electronic device may be eliminated, manufacturing cost may be reduced, and the electronic device may be efficiently designed. Further, according to various embodiments of the disclosure, magnetic north may be determined successfully at the geomagnetic sensor, while it is determined whether the cover has been attached to the electronic device.
- According to various embodiments of the disclosure, for other types of electronic devices, the orientations or positions of components including magnetic members may be identified through the geomagnetic sensor. A double foldable
electronic device 400 as another type of electronic device will be described below. -

electronic device 400 may include a flexible display (not shown) provided to be seated over the front surface (e.g., thefirst surface 410 a) of thefirst housing structure 410, the front surface (e.g., thethird surface 420 a) of thesecond housing structure 420, and the front surface (e.g., thefifth surface 450 a) of thethird housing structure 450, and foldable along according to the folded states of thehousing structures electronic device 400 is fully unfolded such that thefirst housing structure 410, thesecond housing structure 420, and thethird housing structure 450 are on substantially the same plane, the double foldableelectronic device 400 may provide a widest screen to the user, as illustrated inFIG. 11 . - In a foldable housing of the double foldable
electronic device 400 illustrated inFIGS. 11 and 12 , thefirst housing structure 410 and thesecond housing structure 420 may be freely folded around thefirst hinge structure 430 depending on a user manipulation, the action of other external forces, or the angle between thefirst housing structure 410 and thesecond housing structure 420. Separately from or additionally to this operation, in the foldable housing of the double foldableelectronic device 400, thesecond housing structure 420 and thethird housing structure 450 may be freely folded according to a user manipulation, the action of other external forces, or the angle between thesecond housing structure 420 and thethird housing structure 450. The folding operation using thefirst hinge structure 430 and the folding operation using thesecond hinge structure 440 may be performed independently of each other, and simultaneously or at different times. - The double foldable
electronic device 400 illustrated inFIGS. 11 and 12 may include ageomagnetic sensor 460, a firstmagnetic member 470, and a secondmagnetic member 480.

Various positions may be set for thegeomagnetic sensor 460, the firstmagnetic member 470, and the secondmagnetic member 480 according to embodiments. The firstmagnetic member 470 and the secondmagnetic member 480 may be disposed freely in thefirst housing structure 410 and thethird housing structure 450, respectively. However, since when the magnetic members are disposed too close to thegeomagnetic sensor 460, an azimuth error may occur in thegeomagnetic sensor 460, the firstmagnetic member 470 and the secondmagnetic member 480 may be disposed at positions that do not affect magnetic north determination of thegeomagnetic sensor 460. A threshold that affects the magnetic north determination operation from thegeomagnetic sensor 245 may be set for each of three axes (X, Y, and Z axes), and the firstmagnetic member 311 and the secondmagnetic member 321 may be disposed at distances (separation distances) that do not exceed the threshold. - As a guide for methods of disposing the first
magnetic member 470 and the secondmagnetic member 480, the embodiments described before with reference toFIGS. 7A to 8B may be applied. In the drawing, the firstmagnetic member 470 and the secondmagnetic member 480 are shown as disposed on side surfaces of theelectronic device 400, for example, the (3-2)thside surface 415 b and the (9-1)thside surface 455 a, which should not be construed as limiting the disclosure. In addition, while each of the firstmagnetic member 470 and the secondmagnetic member 480 is shown as having a dipole and disposed such that each polarity oriented in parallel to the length direction of a side surface (e.g., the (3-2)thside surface 415 b and the (9-1)thside surface 455 a) of theelectronic device 400, the disclosure is not limited to the illustration. - According to various embodiments, the first
magnetic member 470 and the secondmagnetic member 480 may be disposed to have different polarities. The electronic device according to various embodiments of the disclosure may be provided to perform a function of determining magnetic north as well as a function of identifying a folded state of the double foldable electronic device, without a separate hall IC by applying thegeomagnetic sensor 460 attached for determining magnetic north and a structure in which magnetic members having different polarities are attached in the housing structures. - According to an embodiment, as illustrated in
FIG. 12 , when thefirst housing structure 410 is folded in with respect to thesecond housing structure 420 such that a display disposed on the front surface (e.g., thefirst surface 410 a) of thefirst housing structure 410 and a display disposed on the front surface (e.g., thethird surface 420 a) of thesecond housing structure 420 face each other, the display parts facing each other may be considered to be, for example, in the sleep mode and thus deactivated. When thethird housing structure 450 is folded out with respect to thesecond housing structure 420 so that the rear surface (e.g., thesixth surface 450 b) of thethird housing structure 450 and the rear surface (e.g., thefourth surface 420 b) of thesecond housing structure 420 face each other, a display part disposed on the front surface (e.g., thefifth surface 450 a) of thethird housing structure 450 is exposed to the outside. Therefore, the display part may be considered to be, for example, in the wake-up mode and thus activated. - According to other embodiments, when the
first housing structure 410 is folded out with respect to thesecond housing structure 420, and thethird housing structure 450 is folded in with respect to thesecond housing structure 420, a part of the display may be considered to be, for example, in the wake-up mode and thus activated, while the other part of the display may be considered to be in the sleep mode and thus deactivated. - According to other embodiments, when the
first housing structure 410, thesecond housing structure 420, and thethird housing structure 450 are disposed on substantially the same plane and thus the display is fully unfolded, the display may be considered to be in the wake-up mode and activated. Obviously, the disclosure is not necessarily limited to this embodiment. When no input is generated for a predetermined time even in the fully unfolded state of the display, various embodiments may be applied, such as switching from the wake-up mode to the sleep mode. - As described above, according to various embodiments of the disclosure, some of the functions of the double foldable
electronic device 400 may be activated (e.g., the wake-up mode) or deactivated (e.g., the sleep mode) depending on a direction in which thefirst housing structure 410 is folded with respect to thesecond housing structure 420 or a direction in which thethird housing structure 450 is folded with respect to thesecond housing structure 420. Depending on a direction in which thefirst housing structure 410 is folded with respect to thesecond housing structure 420 or the direction in which and a degree to which thethird housing structure 450 is folded with respect to thesecond housing structure 420, the size of the area of the display exposed to the user may be set in various manners. As the area of the display exposed to the user is activated and a non-exposed area of the display is deactivated, power consumption may be reduced, and user convenience may be increased. To this end, according to various embodiments of the disclosure, thegeomagnetic sensor 460 and the at least twomagnetic members housing structures - An electronic device according to various embodiments of the disclosure, which has an extendable display, may include a foldable electronic device in which at least a part of a display may be folded around a folding area, a slidable electronic device in which at least a part of a display may move linearly, and a rollable electronic device in which at least a part of a display may be rolled.
